HARROW.

SPECIFICATION forming part of Letters Patent No. 453,020, dated May 26,1891.. Application filed January 8, 1891. Serial No. 377,112. (Nomodel.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM D. NAPIER, a citizen of the United States,residing at Mountain Home, in the county of Baxter and State ofArkansas, have invented certain new and useful Improvements in Harrows;and Ido declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being bad to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention has relation to barrows; and it consists in the novelconstruction and arrangement of its parts.

In the accompanying drawings, Figure l is a top view of my invention.Figs. 2 and 3 are side views of my invention, and Fig. 4 is a detailview of the axle 0.

My invention is described as follows: It consists of a harrow A, havingthe hinged wings a. Said harrow and teeth are provided with the usualteeth a. The wings are braced to the harrow A by the rods a attached asshown in Fig. 1. Said wings are further provided with a rope' a withwhich the operator, sitting in the ordinary spring-seat B,can swing saidwings up and back on the harrow A. The outer side of the wings will.rest on the top of the yoke a.

Harrow A is provided with an axle C, having the upper elbow c and thelower elbows o c. On the ends of said axle arejournaled the wheels 0Said harrow has also an axle D, having its ends bent up and forming thearms cl, to the upper ends of which are at tached the front ends of therods d, the rear ends of which are attached to the upper elbow c of theaxle O. Said axle D has the arms (Z pivoted to its middle, and betweensaid arms is journaled the wheel (Z Harrow A is provided with across-piece a on which is secured the spring-seat B and the front endsof the arms I), the rear ends of which are attached to the rear side ofthe said harrow. Said arms I) are provided. with the bearings b, inwhich is journaled the wheel 17 Said wheel is provided with theratchet-extension b and the rim of said wheel is concaved to receive thechain 19 the rear end of which is attached to said wheel and the frontend to the elbow c of the axle C. One of the arms I) is provided with apawl I), one end of which works in the ratchet-extension b, and theother is provided with an angular extension (see Fig. l) to be operatedby the foot. On the axle of wheel I) is. loosely journaled a lever Z),which is adapted to catch in the lugs 12' of said wheel b 7 My inventionis operated as follows: lVhen it is desired to transport the harrowalong a road or from one field to another without engaging the teethwith the ground, the lever b, working in the lugs b of wheel W, is drawnto the rear, and thus, winding the chain 12'' around the periphery ofsaid wheel b the pawl on arm I) will hold the wheel 11 in the desiredposition. hen the chain 12 is drawn back, the elbow c of axle O is alsodrawn back. This will force the elbows c c, on which are the wheels 0down, and as said axle passes under the harrow A (see Fig. 1) saidharrow and teeth will be raised up off the ground, the wheel 61 liftingthe front part of the harrow in a similar manner. (See Fig. 2.) Then thetwo wings are swung back upon the harrow A, and it is then ready fortransportation. When it is desired to engage the teeth with the ground,the operator simply releases the pawl from the ratchet-extension b andthe teeth are thus lowered. (See Fig. 3.)

Having described my invention, what I claim as new, and desire to securebyLetters Patent, is-

In combination with a harrow A, having the crosspiece a and wings a,axle 0, having the elbows c and c and wheels 0 axle D, having the arms(Z and caster d rods cl, arms I), having the bearings 19, wheel Z2having the ratchet-extension b chain 11*, pawl 6 and lugs b lever Z)",arms of, rope a and yoke a, all substantially as shown and described,and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.
